    Yeah I need to get my Saturn 2 up and running again. Just haven’t had time. I keep it in the garage but there isn’t any ventilation in there. I ordered the new stand alone Elegoo carbon filter but it won’t arrive until august. Been considering cutting a hole in a wall and adding active ventilation.

    So in theory once it’s cured and cleaned it’s solid but the reality is we don’t really know that to be true. And my concern here is this isn’t something you might pick up now and again. This is something you’ll be in contact with hours at a time. Sweat and oil mixing into it.

    The best evidence I have on this is the fact that transparent resins often, if not sealed in a UV blocking clear coat, turn yellow. And traditional resins if not similarly sealed or sealed in an opaque layer (primer and paint) will crack if left exposed to UV light. That tells me the chemical reaction can continue and that they aren’t as inert as say the resins used in wood turning that have a chemical catalyst.

    Just want folks to be safe! But I’m betting you know the risks better than most.

    So… I don’t want to be a buzz kill.

    Have you sealed the resin? Much like urushiol and latex if you expose yourself to resin enough you can develop an allergy even if you didn’t have one before. No resin is body safe. And the thing with transparent/translucent resins is we want to show them off. Because it looks cool! But it’s poison. When printing miniatures and statues you intend to paint it’s easy. You have to primer them to get the paint to stick so you don’t have to worry as much.

    Anyway rant aside. It looks cool!





  • Dude my wife got it on her face last year. All her family asks her to do their gardening because I retired her. So frustrating.

    Little know detail - mango trees produce urushiol! The mango we buy has been bred to reduce this but if you are very sensitive you can have a reaction from the skin of the fruit.

    Even lesser known detail - my army of siblings and I are mostly immune to it. If we get exposed enough we will start reacting so I don’t push my luck
